NGK Ruthenium 1 Step Colder Spark Plugs HX LTR7BHX 95605 (Single Plug)

Packaging was excellent, protecting the fragile spark plugs. Shipping was quick, and hassle-free.

I bought the spark plugs when I ordered my tune ans SCT almost 2 years ago..

Everything has been great with MPT!

Excellent service, communication, tips and recommendations!

Thanks you James, Ross, all the guys!

Good spark plugs, no issues and it fixed my misfiring. They came at .31 give or take .02 , make sure you get the tool for consistent spacing. I brought my to .28 MPT is very fast at sending stuff out

The plugs really smoothed out my idle and got rid of the full throttle surge I was feeling. Paired with the tune and the 170 degree thermostat it’s a different truck. I love the power and quicker shifts. So much fun to leave people in the rear view.

Great product, these went very well with the SCT preloaded tuner, gave the 14 a new spark.

Great plugs if your running a hotter tune

Mpt is simply the best period!! Anything they recommend is extremely good.

Swapped out the spark plugs when changing out the fuel injectors since we have to take the intake plenum to get the passenger side plugs…me being finger happy I bought these not looking at the pre gap so I did have to open up the gap to fords spec. Retuned for the new injectors and running e85. It is running much better and I’m getting better MPG.

Hands down the best company for performance, tunes, accessories, merch best costumer service would never chose any other company but MPT

Great plugs and the tune is working awesome thanks to mpt guys

They have spark plugs in stock and were helpful

Came perfectly gapped

Better ignition and smoother acceleration.

These plugs made my truck run the best it ever has. Definitely recommend. mpt shipped these right away

👍

Great-service, with fast shipping!

The truck was due for spark plugs, and since MPT tuned my truck and recommends cooler plugs, I got these and they've been great. Very happy with all my MPT interactions.

The plugs came as expected with spot on pre`gapping. Pricing was great and MPT provided confidence in.my purchase apart from all the various recommendations on the internet. MPT built my tune which performs flawlessly and continues to provide guidance and quality recommendations keeping my F150 3.5L ecoboost at the top of its game.

Mods: S&B Cold Air Intake, SCT X-4, , Catch CanAfter talking to the guys at MPT about what I was wanting for/out of my truck, they nailed the tunes down last year and I've been incredibly impressed with the results and professionalism of the team. When it came time to change out my spark plugs, once again I reached out to MPT because it was a no brainer. I reached out to MPT a few weeks back and they took care of me since I was out of state and needed the plugs before continuing on my trip for my 18 F-150 2.7 Ecoboost. Heck it only took me a day to drive to North Arkansas from East Texas and the plugs beat me there! My truck runs much smoother across the board, and when she comes into boost I know the right plug is in there and she doesn't miss a beat! For those of you who have built cars, engines, had them tuned, etc. over the years, you know that if your tuner tells you to go with something such as certain spark plug(s), or fuel, or exhaust, you tend to take their word on it because this is what they do, all day every day. That being said if you're thinking about getting new plugs for your ride, make the call and deal with MPT and get them ordered today because you can have the baddest motor, the stickiest tires, etc. etc. but a bad/fouled up spark plug can make a real bad day real fast. Thanks again to the team at MPT, it's going to be Intercooler time very soon!

I was suffering from misfires with only 25k on stock plugs, These seem to have totally cured those issues and seems to have better power. Just seem to be a bit pricey.
